To all whom it may concern: (1 I Be it known that'l, HAROLD NEWTON COX, a citizen of the United- States, resid ing" at 39$.McDo'nough street, borough er Brooklyn, county ot;liiiigs,. city and State of New York, have invented a certain new and useful Improvement 1n Windmill l)Y1CQS,.,Of

wh,ieh the following is aspecification.

invention relates to improvements in windmill devices as applied to the generation speed wheel is connected directly to the generator;' and uniform speed obtainedby the. automatic operation. of a governing vane-or tail which keeps'said wheel flat against the.

fwind 'up. to a predetermined speed after which it is turned away irom the wind sulliciently to pre;\ 'ent excessive or suicidal speeds. .Voltage of generator to be made proportional to speed of wheel by shunting 'li'eld currentlroni,line urrent thus keeping held current 'eonstnnt. As the speed of the generator increases, the number of storage rolls in series w-ithsaid generator is to be antom ati'cally increased.

I I 'llieelectiical features of my invention I propose to attain by employing such devices 1 as are already prodncwt.

W hile, the; inechanieal features 1 accmnilish by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a partiallongitudinal section of the/entire device, the wheel to the left and the vane to the right. Fig. 2 is on the right aone-lmll rear elevation, and on the left a one hall combined l'ront elevation and partial cross section, and Fig. 3 is a. top view as the dcvicewould appear with hall ol' the genorator and carriage removed. 7

'Snrnlar letters refer to similar parts througl'rout the several views.

-' Plate. A theb'ed plate-oi n'iy device, is so "cured to and forms the top ol'the windmill tower. -l have provided on its upper surface an annular ehannel containing antilriction rollers'and guide rings as shown at l Plate rests onthe rollers B, free to rotatein a-ihori-zontal' direction, and is provided.

-with a downwardly projecting hollow shaft passing through a central hole in plate A as. shown at I). This said shalt l) contains the wiring, from the generator-X to the conductor. E 'by =nieans of which (d'ecliienl connection is obtained lwhveen the-said generator X and'a storage battery or other-system. 'lhis said Specification of Letters Patent.

J as its pivot actuated through the integral I arm hereinafter referred to. p

Plate L acting as a carriage forthe genera-- tor X is rovided on its under side w1th longitudina channels containing antifriction rollcrs'O.(Figrs. 2 and 3) and is free to move back and forth on plate (3, said movement bcingguidedhy lips on the'cdges of said plate L, running in corresponding grooves on the sides of plate (2, the length of this movement is restricted bythe lugs M and N at the ends-cf said plate '0. The rear end of carriage L is connected by. a connecting rod R with the lever arm K of the vane (Figs. 1 and 3). thcvane. 1 To the rear'undersidc of carriage L is secured achain passing over a roller anddownward through the hollow shaft D' carrying a weight F abovementioned, whose function is to hold the said carriage L pressed against the forward lug M of plate C (Fig. 1.). And when in this position the wheel P (Fig. 1)'is at right angles with the vans and at right an A movement of]; causes a movement of gles to the direction of the wind. This posil tion is retained as long as the weightFis sufficient to withstand the pressure of the wind on the wheel P, which is predetermined within proper speed limits and when this is eX,- eeeded the: excessive pressure on. the wheel P- will lift the wcightand cause a backward l movement of the carriage L and by its connectionthrough rod R with the arm K, a consequent change in the position of the vane, and the-wheel will lie partially turned away from the windwso that the pressure on the wheel P and in consequence its speed will be automatically regulated and will so continue until carriage L has been pushed back to a 1 point when the generator X occupies thepositiou indicated hv the dotted line S (Fig. 1). The vane then becomes parallel with the wheel and both parallel to the direction of the wind when rotation of wheel P ceases. A reduction in the pressure of the wind permits a forward movement of. carriage L a eonscins qu-entmovement of the vane which again I throws wheel P into operation.
